Our world is ruled by information. Information is required
for every task that we perform. 
Information is converted to data and this can be transmitted easily over
wires, cables or satellites as bits of zeroes and ones.
With the advancements in telecommunication
data stored in one place is easily accessible around the world, but there is one
major concern of security. With money
acquiring a digital form the need for security is increased more because,
nobody wants to give out his credit card number to a service provider to be
used by malicious agents.</p>

<p>
Security is provided
by the use of cryptography to encrypt the transmitted data.
Steganography can be considered as a form of
cryptography where the fact that a message is present is itself not evident to
any casual observer. This ensures more
security because an eavesdropper is not looking for a secret message in an
innocent looking picture.</p>

<p>
The project aims to
create steganography software that can be used to encode and decode messages
into and from images.
